Book Description
Confronting contemporary African art's awkward coexistence with earlier African art as "ethnographic artifact," Geo-Graphics celebrates the flourishing of African art on the international circuit, while simultaneously asserting its ancestry and critiquing the valorization of heritage. David Adjaye's photographs of African capitals and an examination of contemporary African art centers further contextualize the continent's recent cultural transformations.

Book Description
This book celebrates the relaunch of the African Pollen Database, presents state-of-the-art of modern and ancient pollen data from sub-Saharan Africa, and promotes Open Access science. Pollen grains are powerful tools for the study of past vegetation dynamics because they preserve well within sedimentary deposits and have a huge diversity in ornamentation that allows different taxa to be determined. The reconstruction of past vegetation from the examination of ancient pollen records thus can be used to characterize the nature of past landscapes (e.g. abundance of forests vs. grasslands), provide insights into changes in biodiversity, and gain empirical evidence of vegetation response to climatic change and human activity. In this, the 35th Volume of "Palaeoecology of Africa", we bring together new data and extensive synthetic reviews to provide novel insights into the relationships between human evolution, human activity, climate change and vegetation dynamics during the Quaternary, the last 2.6 million years. Current and ongoing climate and land-use change is exerting pressure on modern vegetation formations and threatening the livelihoods and wellbeing of many peoples in Africa. In this book the focus is on the Quaternary because it is during this geological period that the modern vegetation formations developed into their current configurations against a backdrop of high magnitude global climate change (glacial-interglacial cycles), human evolution, and a growing human land-use footprint. In this book the latest information is presented and collated from around the African continent to parameterize past vegetation states, identify the drivers of vegetation change, and assess the vegetation resilience to change. To achieve this research from two broad themes are covered: (i) the present is the key to the past (i.e. studies which improve our understanding of modern environments so that we can better interpret evidence from the past), and (ii) the past is the key to the future (i.e. studies which unlock information on how and why vegetation changed in the past so one can better anticipate trajectories of future change). This Open Access book will provide a strong foundation for future research exploring past ecological, environmental and climatic change within Africa and the surrounding islands. The book is organized regionally (covering western, eastern, central, and southern Africa) and it contains specialized articles focused on particular topics (such as modern pollen-vegetation relationships and fire as a driver of vegetation change), as well as regional and pan-African syntheses drawing together decades of research to assess key scientific questions (including the role of climate in driving vegetation change and the role of vegetation change in human evolution). These articles will be useful to students and teachers from high school to the highest level of university who are interested in the origins and dynamics of vegetation in Africa. Furthermore, it is also meant to provide societally relevant information that can act as an inspiration for the development of sustainable management practices for the future.

Book Description
SIMPLE questions often help us to understand problems better; and I think it indispensable, at the beginning of this work, to ask a question which appears simple in the extreme: "What is grazing?" The answer is generally as follows: "Causing grass to be eaten by an animal." That is correct! But here is another answer which, to my mind, is more realistic: "Causing the grass and the animal to meet." Since this book is almost exclusively concerned with grazing by cattle, I propose the following definition to the reader, requesting him to allow it to become well impressed upon his mind: Grazing is the meeting of cow and grass. It is by satisfying as far as possible the demands of both parties that we will arrive at a rational grazing, which will provide us with maximum productivity on the part of the grass while at the same time allowing the cow to give optimum performance.

Book Description
Cultural landscapes are at the interface between nature and culture. They represent the permanent interaction between humans and their environment, shaping the surface of the earth. With the rapid social and economic development cultural landscapes belong to the most fragile and threatened sites on earth. Adapted protection and proper management is urgently needed. Since 1992 outstanding cultural landscapes can be protected under the World Heritage Convention. Thus, the World Heritage Convention is the first international legal instrument recognizing and safeguarding this type of property for future generations. This important step has led to enhanced international and national recognition. The present volume aims to contribute to enhanced protection and management of cultural landscapes around the world. It furthermore highlights in a truly interdisciplinary approach some of the most outstanding cultural landscapes of universal value in their geocultural and environmental context.

Book Description
"Congolese photographer and videographer Sammy Baloji explores the "beautiful time" when the labor of hardworking Congolese built a flourishing copper mining industry in what is now the Katanga region of the Democratic Republic of the Congo. Following independence in the 1960s, this industry suffered greatly under mismanagement by corrupt governments. Baloji's collages and photographs bring together images from the past and the present day to interrogate the meaning of memory."
